[Luke 37119]

I just tried installing emby on centos 7 in esxi.  512MB ram, 2 vcpu.  I was able to complete the wizard with no issues.

 

Which hypervisor are you using?

 

EDIT:  I used the minimal version of centos 7.  It was a clean install.  Enable epel-release.  Installed emby. Downloaded 64bit ffmpeg daily version.

I just built this vm, and did nothing else except try to install Emby

Interesting, thanks for the info.

[dcook 265]

I just built another VM, same as the last one 600MB ram, 1CPU and this time I installed Ubuntu 16.04

I followed the steps here: https://software.opensuse.org/download.html?project=home%3Aemby&package=emby-server

 

The setup wizard completed without any errors.  

Also I was not even prompted during the setup wizard to install and define path for ffmpeg, I am not sure why, perhaps Ubuntu includes ffmpeg by default?

 

Either way, looks like the issue with Out of Memory is specific to Centos 7.3

[Luke 37119]

@@dcook thanks for the investigation !

[dcook 265]

When I built my previous Centos and Ubuntu VM's they did not have any /swap space

 

I built a new Centos VM, same specs (600MB Ram, 1CPU) but this time I added 1GB /swap

 

The Emby Setup Wizard completed fine and ffmpeg plays without any "out of memory errors"

 

While something is playing if I check I can see that some of the /swap space is being used.

So looks like not have any /swap on my Centos7 Vm's is what caused the issue.

 

Interesting aspect is that Ubuntu also did not have any /swap and the Emby Setup Wizard completed fine?

 

@kjp4756

When you built your Centos7 VM did you have any /swap ?

[kjp4756 41]

Honestly I am not sure if I had swap or not.  I used the minimal iso and used defaults for everything.

 

EDIT:  Looks like there is swap on a default install.  923MB according to free -h
